Practical Example: Suppose you wrote this html "app" and want to know if the client supports multitouch input. If it does, the buttons become expendable thus may be hidden - which is highly desirable on small screens. Of course, putting users through a multitouch capability test after installation would be an option, however that's a quirky solution.
Being aware of the current w3c candidate recommendation on touch events, and things like the app manifest (which deals only with caching requirements), i would like to ask:
- is there any standard (=non-proprietary), even as draft or recommendation for a mechanism that allows for negotiation of touch input capabilities between an app and client?
- If no - which would be the appropriate "tree to bark at", in order to spark discussion with the right organisation / people (or maybe it has been discussed before and rejected for a good reason)?
